DE FORREST B. OAlLIN, OF MANKATO, MINNESOTA,

THERAPEUTIC OVEN.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed December 17,1906. Serial N9. 848,264.

To all whom it may concern:

Be it known that I, DE FoRREsr B. GATLIN, a citizen of the UnitedStates, residing at Mankato, in the county of Blue Earth and State ofMinnesota, have invented certain new and useful Improvements inTherapeutic Ovens, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to improvements in apparatus by which invalids maybe subjected to currents of dry, hot air; and one object of my inventionis to provide an apparatus of the class just described, which will besimple in construction and efficacious in its remedial effects.

Another object of my invention lies in the provision of means forcontrolling and maintaining a temperature sufficiently high for theattainment of maximum of beneficial effects.

One feature of my invention resides in the arrangement of parts wherebythe air is introduced into the box-like compartment within which thepatient seats himself, and by which the air is heated. Heretofore, sofar as known to me, the burners or other heating devices have beenplaced in the compartment itself, or in niche-like chambers in thecompartment. In carrying out my invention the floor of the compartmentis provided with openings through which the hot air is admitted from anair-box mounted below the floor of the compartment; the air-box beingheated by suitable burners.

Another feature of my invention consists in the provision of means forlocalizing the application of the heat to the lower part of the body ofthe patient. To effect this a casing is provided which is mounted in theinterior of the compartment and fits around the body of the patient justabove his waist, or there abouts. To distribute the heat as much aspossible over the body, air-ducts are provided which lead up from theair-box to about the middle of the compartment.

Other features of my invention will be alluded to in the descriptionwhich follows hereinafter.

In the drawings illustrating the principle of my in vention and the bestmode now known to me of applying that principle, Figure 1 is a frontelevation of my new therapeutic oven, the doors being shown closed; Fig.2 is a side-elevation of the same; Fig. 3 is a front view with the upperdoors open and the auxiliary casing in place; Fig. 4 is a front viewwith the auxiliary casing removed and the doors open; and Figs. 5, 6 and7 are details hereinafter referred to.

The box-like compartment is made up of the back 1),

- floor 6, sides 2, top 5, upper doors b and lower door 0 From near themiddle of the front edge of each of the side walls 2, the front edgeslants upwardly and rearwardly after the manner of an ordinary pianocase or box; and to this slanting portion of the front edge is hinged adoor 1) formed with a notch a which cooperates with the recess (2* cutin the top 5 to form an opening through which projects the head of thepatient. To

' the lower front edge of one of the side walls 2 is hinged the lowerdoor 0. The upper doors I) are secured together by the latch members 3,while the lower door 0 is secured to the other of the side walls 2 bythe latch 4. To the top 5 of the compartment is secured one end of eachof the chains 1', the other end of which is secured to one of the doorsb. Each chain i serves to limit the outward travel of one of the upperdoors b, and to support it in its open position.

On each of the inner side walls is secured a bracket n which supportsthe top of one of the auxiliary casing members 5 (see Fig. 7), the loweredge of which rests upon the upper edge or-the lower door a. The top ofeach part of the auxiliary casing g is formed with a recess, the tworecesses combining to form an opening h through which the body of thepatient passes. Each part 9 is further provided with a handle j and thetwo parts are secured together by means of a latch device 7. By makingthe casing g in two parts, it is more read ily handled. The auxiliarycasing enables the application of the heat to be localized, as isdesirable in those cases in which the lower limbs are to receive thetreatment.

As is shown in Fig. 2, an air valve is is mounted in the side wall 2near the top thereof. The inner face of each side Wall 2 carries anair-duct m the upper end of which opens just below the bracket 11. Thefloor 6 is formed with a central opening 0* just above which is mountedthe iron revolving stool Z; and with two side openings 0. The floor 6 isof galvanized iron, preferably, with inch wood flooring below thegalvanized iron for stiffness of structure.

To the bottom of the floor 6 and underneath the latter is mounted anair-box d the hot-plate p of which is exposed to the flame from theburners 3 fed through the pipes to leading from the tanks 6 whichcontain the liquid fuel: To make room for this air-box d and the burnerss underneath the box-like compartment, the latter is mounted upon theiron legs f, which are suitably braced, as shown in the drawings. Thechamber 8 above the hot-plate p communicates directly with the centralopening 0* and the air-ducts m and contains the galvanized iron boxes rin which are the fines x that lead to the openings 0 on each side of thestool.

I claim:

1. A therapeutic oven made up of a box-like compartment the top of whichis provided with an opening through which projects the head of thepatient an auxiliary casing mounted in said compartment and fittingaround the body of the patient for the localization of the heat to thelower limbs; and means for introducing hot air into said compartment.

2. A therapeutic oven made up of a box-like compart- 'Inent providedwith a door; an auxiliary casing supported by the walls of saidcompartment and the top of said door, said casing being formed with arecess within which fits the body of the patient; and air-heatingdevices connected with said compartment.

3. A therapeutic oven made up of a box-like compartment; an auxiliarycasing mounted therein and formed with a recess in its top within whichfits the patients' body air-ducts leading into said compartment andopening below the top of said casing; and air-heating devices connectedwith said air-ducts.

In testimony whereof I hereunto set my hand in the presence of twowitnesses this fourth day of December, A. D., 1906.
